SPECIFICATION forming part of Letters Patent No. 608,960, dated August 9, 1898. Application filed November 6, 1897. Serial No. 657,630. (No model.)

To all whom it may concern:

Be it known that I, HENRY FOULOIS, a citizen of the United States, residing at Washington Depot, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Siphons; and I do hereby declare the following to be a full, clear, and exact description of the illvention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

Myobject is to provide an improved siphon of simple and inexpensive construction especially adapted for drawing off oil from barrels into tanks, whereby the flow of the liquid can be readily started without danger or inconvenience to the operator.

The foregoing object is accomplished by the provision of a siphon comprising a main tube having a bend of peculiar shape and a blow-tube leading into the main tube, together with a novel form of valve disposed in proper relation to the blow-tube, as will be set forth in detail hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of my improved siphon; Fig. 2, a sectional elevation, and Fig. 3 a detail of the cap and valve.

The main pipe of the siphon consists of two legs 1 and 2, disposed at an angle of about sixty degrees to each other. The bend or junction of these legs is enlarged vertically at 3, so that the pipe is rendered substantially elliptical at this point, which is for the purpose of allowing an easier flow, and this is an advantageous feature of the invention.

The leg 2 has a screw-threaded end 4. for engagement with the coupling 5 of ,a long flexible tube 6, which is inserted in the receiving vessel or tank during the siphoning operation. Fitted over the lower end of leg 1 is a removable cap 7, having feet 8 at its lower extremity. Within the cap is an unbalanced flap-valve 9, whose larger portion normally rests on a stop 10, projecting from the inside of the cap.

Ablow-tube (shown at 11) extends along the side of leg 1 and has a mouthpiece 12 at its upper end, while the lower end of this tube opens into the leg 1 at the point 11 orimmediately above the flap-valve.

The operation is as follows: The leg 1 is first immersed in the fluid in the barrel of oil, after which the operator blows forcibly in mouthpiece 12. This causes the flap-valve to close, and at the same time the fluid above the valve in leg 1 is ejected through the flexible tube by the air-pressure. The operator then plugs mouthpiece 12 to prevent any air from entering therein, and the vacuum occasioned by the expulsion of the fluid causes the valve to reopen and the oil to flow upwardly in a continuous stream. The advantage of employing a removable cap is that cleaning of the receiving and blow tubes is rendered easy.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A siphon comprising two legs, an eccentrically-pivoted valve in the receiving-leg, a

stop for saidvalve, and a blow-tube communicating with the receiving-leg above the valve.

2. A siphon, comprising two legs, an unbalanced fiap-valve in the receiving-leg, a stop for said valve, and a blow-tube communicating with the receiving-leg immediately above the valve.

3. A siphon, comprising tubular receiving and delivery legs in communication, a removable cap fitted on the end of the receiving-leg, an unbalanced flap-valve in said cap,

a stop in the cap adapted to engage the flapvalve, and a blow-tube communicating with the receiving-leg above the valve.

In testimony whereof I affix my signature in presence of two witnesses.
